Our primary concern is with your soil. To grow healthy plants, you need a healthy soil, one that has abundant and diverse populations of microorganisms and other species, one that has an open soil structure for water movement and oxygen exchange, one that has available nutrients that can be easily taken up by the plant, and you need to minimize external stresses on the plant.

There are three aspects of the soil -- biological (microorganisms and other animal species), physical (soil aggregation, moisture holding capacity, etc.), and chemical (nutrients, toxic substances, etc.)

Our primary products have a significant influence on these three aspects of soil; these can generally be classified as primary effects (P) or as secondary effects (S) as indicated below:
